Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 312,777,325, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 312,777,325 | |
| -1 | -312,777,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 312,777,325.
Example:
1 x 312,777,325 = 312,777,325
and
-1 x -312,777,325 = 312,777,325
Notice both answers equal 312,777,325
With that explanation out of the way, let's continue. Next, we take the number 312,777,325 and divide it by 2:
312,777,325 ÷ 2 = 156,388,662.5
If the quotient is a whole number, then 2 and 156,388,662.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 312,777,325 | |
| -1 | -312,777,325 |
Now, we try dividing 312,777,325 by 3:
312,777,325 ÷ 3 = 104,259,108.3333
If the quotient is a whole number, then 3 and 104,259,108.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 312,777,325 | |
| -1 | -312,777,325 |
Let's try dividing by 4:
312,777,325 ÷ 4 = 78,194,331.25
If the quotient is a whole number, then 4 and 78,194,331.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 312,777,325 | |
| -1 | 312,777,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 725 | 1,015 | 5,075 | 61,631 | 308,155 | 431,417 | 1,540,775 | 1,787,299 | 2,157,085 | 8,936,495 | 10,785,425 | 12,511,093 | 44,682,475 | 62,555,465 | 312,777,325 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -725 | -1,015 | -5,075 | -61,631 | -308,155 | -431,417 | -1,540,775 | -1,787,299 | -2,157,085 | -8,936,495 | -10,785,425 | -12,511,093 | -44,682,475 | -62,555,465 | -312,777,325 |
